Didn't you make a post about this a while back?

Every shot, off target, blocked, saved, hits the post, scored, has a xG probability. Yes, those shots had a low probability of us scoring from them. On average, we would have only scored 1 to 2 goals from those chances. That's not unusual: We scored from a few low probability shots, scoring from difficult chances, yet miss a few chances with a higher probability. It chances one's perception. That's why I like xG: it takes out the subjectivity we all see. Just imagine a penalty: everyone should be scoring every time, but it doesn't work like that; If you add up all the penalties taken over the last few decades, 79% are scored (0.79 xG). In a single match Tavernier can score 2 penalties, over-performing his xG, but over the course of the season he will score around 79% of his penalties.

Incredibly efficient. xG is based on historical data: to put it simply, it is based on how many times a goal has been scored from a certain position in the past. (In reality an xG model takes into account many variables, not just position). For example, Fabio Silva's shot had an xG of 0.16, meaning that out of the thousands of past shots from that position, a goal has been scored 16% of the time. You won't see many goals from that position, compared to Dessers' second, for example (0.35 xG). xG fluctuates match to match (consider the previous match where we had an xG of 4.9, yet only scored 3, against County) , but over the course of several games it is fairly accurate in predicting how many goals we score. Remember how I said Dessers has an xG of 13 for the season, and has scored 12 in reality. It's fairly close, but I would predict these numbers will come closer over the remainder of the season.
